To all 107mm it may concern:

Be it known that I, HARRY BRIDGMAN SMITH, a citizen of the UnitedStates, and resident of Brooklyn, inthe county of Kings and State of NewYork, have invented certain new and useful Improvements in Method ofMaking Covered Paper Boxes, of which the following is a sp eilicatlon.

My present invention which is a cont1nu ation in part of my co-pendmgapphcation Serial No. 254,630, filed September 18, 1918, relatesgenerally to the art of making covered paper boxes, such as are nowcommonly employed in packaging various articles or products ofmerchandise, as, candy, soap, articles of wearing apparel and othercommodities.

One object of the invention is to provide an entirely new method ofmaking covered paper or paper-board box shells of known types as well ascertain distinctly new types.

A further object of the invention is to provide a method of makingcovered paper boxes from an assembly consisting of a shell blank havinga body portion and side and end wings and a cover blank of greaterdimensions than the shell blank wherein many of the difficultiesheretofore encountered in making covered paper boxes are entirelyobviated, prominent among such difliculties being the natural curlingtendency of the cover material when moist adhesive is applied thereto.

Another object of the inventlon is to provide for accurate registrationof the box shell blank with its wrapper blank in order, that the lattermay be more neatly applied.

Other more or less important objects are contemplated and provided for,as will be made clear in the detailed description to follow.

According tothe methods and machines now generally employed in themanufacture of covered paper boxes, the cut or cornered box shell blanksare first bent or folded into box form, the corners stayed with suitablecorner-staying material, and the covering blank or wrapper which hasadhesive applied to one face thereof is then applied to the outer wallsof the box shell,

sometimes by hand and sometimes by machinery. In some instances it hasbeen proposed to eliminate the cornerstaying operation, but in all suchcases, so far as I am aware, it has been the practice to first fold thebox shell into box form and then apply a freshly gummed or gluedcovering blank or wrapper thereto.

Many attempts have been made to provide a continuous method and also toproduce an entirely automatic machine for making covered paper boxes ofthe type referred to. In every instance, so far as I am aware, theautomatic machines heretofore proposed include in their organization amechanism for gumming the thin wrapper blanks; instrumentalities forapplying the gummed wrapper blanks to the box shells; and mechanism fortransporting the gummed wrapper blanks from the gumming mechanism to thebox covering instrumentalitics. Some of the machines also include meansfor automatically feeding thereto the stayed box shells to be covered.

Great ditficulties have been encountered in the attempts heretofore madeto successfully operate machines of these types, due among other thingsto the tendency of the thin paper covering blanks to curl immediatelyfresh gum or glue is applied to a face thereof, resulting in much badwork and waste. Because of this curling of the blanks, the consequentwaste, and other troubles, including imperfect registration, theseantomatic machines have not been successful where attempts have beenmade to operate them commercially.

Many attempts have been made to prevent or counteract this curlingtendency of the blanks resulting from the application there to of fluidgum or adhesive. In some cases the blanks have been steamed or otherwisemoistened during or after the application of the glue in "order to killthe curling tendency. In others an attempt has been made to hold theglued wrapper blanks flat by mechanical means as they pass from thegumming mechanism to the wrapper applying mechanism. In others, attemptshave been made to so organize the machines that the gumming mechanismwould be arranged close up to the wrapper applying mechanism with theobject of delivering the wrappers quickly and before they had anopportunity to curl. \Vhile some of these various attempt to obviate theblank curl ing tendency may have proved satisfactory as to thisparticular item, the means suggested besides being complicated broughtabout numerous new difficulties, and so far as I am aware, a atisfactoryautomatic machine has not yet been produced, and the old practice ofemploying separate hand operators to feed the blanks to the gummingmachine and also to the operator of the cover-applying machine is stillcarried on, notwithstanding the slowness and increased expense of suchprocedure.

I have discovered after extensive and costly experiments, that thepreviously existing difficulties which have been encountered due to thecurling tendency of the wrapper blanks when fresh adhesive is appliedthereto, as well as the many other difficulties, including imperfectregistration, are entirely obviated or overcome and the wrapper blanksmore .accurately, neatly, quickly and cheaply applied, by first applyingthe adhesive to the relatively stifi' box shell blank (which will notcurl appreciably when moistened with adhesive), and by then applying theungummed wrapper blank to the gummed face of the box shell blank toprovide a box forming assembly consisting of a box shell blank and anattached cover blank which may then be folded into box form. Such aprocedure, I have discovered, not only overcomes the objections incidentto the curling of the cover blanks as described as well as otherobjections, but very materially simplifies and cheapens other operationsincident to the formation of the finished box.

So far as I am aware I am the first in the art of making covered boxes,to'suggest and provide for the application of the cover or wrapperafiixing adhesive to the relatively stiff box blank direct, instead ofto the thin and flexible wrapper blank, for the purpose stated, and Itherefore lay claim to this procedure broadly.

I have also discovered that the box forming and wrapper applyingoperations may be more rapidly, cheaply, accurately and expeditiouslyperformed by first producing what I will term, an embryo box formingassembly, consisting of a substantially flat box shell blank and anapplied cover or wrapper blank with opposite marginal edges of the coverblank folded over opposite edges of the shell blank and adhesivelyaffixed thereto. The assembly thus produced may then be folded into boxform and main method I first apply adhesive material to the flat orunfolded box shell blank direct, the adhesive being applied to saidblank in spots or zones, as by stencilling, or over the entire facethereof, and in some instances in spots of zones applied to both faces,or I these elements are substantially flat, and I also inturn and afiixmarginal portions and the wrapper blank to certain of the adhesive zonesor stencil lines of the shell blank while these elements aresubstantially flat, thereby producing what I have termed an embryo boxforming assembly.

By the procedure described it will be seen that the operations ofcovering the box shell blank, including a part of the marginal turn-inare actually completed before said blank is folded into the final boxform.

I have demonstrated that I can produce, according to my improved method,and with an apparatus designed to carry out said method, covered paperboxes of various kinds, including the so-called tight wrapped and loosewrapped boxes, as well as other kinds, more economically, in greaterquantities and of better and more uniform quality, than by any othermethod or apparatus heretofore employed or provided.

In order to enable others skilled in the art to understand and practicemy said invention, I will now proceed to describe a preferred embodimentthereof, but I wish it distinctly understood that this showing is merelyillustrative or by way of example and is not, therefore, to beconsidered in any way restrictive, except as I may be restricted by theterms of the appended claims, as it will be perfectly obvious to othersreading this specification in connection with the appended drawings,that changes, variations or additions may be made both to the method andto the apparatus without departing from the broad spirit of theinvention.

In order that the full scope of the invention may be understood andappreciated I have elected to show in the accompanying drawings apreferred procedure employed in making several different types ofcovered boxes, including tight and loose" wrapped, but, I do not wish tobe understood as limiting myself to these specific types as obviouslyothers may be made by the same procedure or slight variations thereofwithout departing from the spirit of the invention, as will hereinaftermore fully appear.

Three different types of boxes have been illustrated by way of examples.These are shown in completed form in Figures 9, 18 and 27. The twoformer are of the loose wrap variety, so-called because the cover blankis wrapped loosely about the exterior of the box shell; and the other isof the tight wrap variety, so-called because the wrapper is gluedthroughout its entire area to the exterior of the box shell.

All of the boxes shown are made from box shell blanks having corner lapswhich are folded inward toward each other at the ends of the finishedbox to strengthen the corners thereof, and which, together with otherportions of the blank form multiply box wall ends. In some cases thesecorner laps are located interiorly of the box shell, as in the boxillustrated in Figure 9, while in others the corner laps are locatedexteriorly of the box shell, as in the boxes illustrated in Figures 18and 27. These differences in the location of the corner laps areillustra tive of some of the variations of which my improved method issusceptible and the results obtained from such variations, namely,different types or styles of boxes. Of course the same method may beemployed in making boxes wherein the shell blank is not provided withcorner laps.

I will first describe the steps or operations performed in making eachof the three types of boxes herein illustrated and will then describeone form of mechanism I have elected to show as a preferred embodimentof mechanical means for performing such steps or operations, it beingunderstood that in each case the first operation is to form an embryobox forming assembly consisting of a substantially fiat box shell blank,usually of relatively stiff card-board or box-board stock, creased orscored and slit or cornered as usual, and an attached cover blank ofrelatively thin paper or other readily foldable material and which issometimes plain and sometimes decorated by printing and embossing,either or both, said cover blank being usually cornered.

In Figures 1 to 9 inclusive I have illustrated the various steps assuccessively performed in making one type of loose wrapped box accordingto my improved method. This is a distinctly new type of box, one newfeature residing in the fact that portions of the wrapper blank areinfolded at the ends of the box and lie in between the plies of themultiply end walls formed by the corner laps and adjacent overlying endwings at the ends of the box, the said infolded portions covering theraw edges of the end wings as will more fully hereinafter appear.

In this type of box S designates the box shell blank, which is usuallyof stiff cardboard or box-board material and V7 designates the wrapperor cover blank, which is usually of plain or ornamental finishing paper.

The shell blank S, in the instance illustrated, is out and scored orcreased to provide the usual folding lines, and consists of a bodyportion (1., having integral side wings Z2, corner laps 0 and end wings(Z. The side and end wings and corner laps, when folded at right anglesto the body portion a, of the blank, form a box shell having multi-plyend walls, the corner laps in this particular style of box being locatedinteriorly thereof.

Shell blanks of this type are now in common use, but the usual practicehas been to apply the cover or wrapper blank thereto, after the shellblank has been completely set up into box form and stayed at the cornersalthough in some instances the cover has been applied to the folded boxshell without first corner staying the latter. According to my improvedmethod, I propose to apply the wrapper blank to the shell blank whilethe latter is substantially flat, producing a flat covered assemblywhich is afterwards folded and set up into box form.

The wrapper blank IV in the instance shown consists of a sheet ofrelatively thin and readily foldable paper or other flexible materialand is of general cruciform shape, and of greater dimensions than theshell blank S, leaving marginal portions that may be folded about themarginal edges of the shell blank, as will presently appear.

In making the flat assembly consisting of the relatively stiff shellblank and the wrapper blank, according to my improved method, I firstapply zones or stripes of adhesive e, to one face of the shell blankaround the marginal edges thereof, as shown in Figure 1. This blank inits flat form is then superposed in proper registration relation upon anungummed wrapper or cover blank of the type referred to, as shown inFigure 2. The two blanks having been combined as shown in said figure,and while they are still in a flat condition, I inturn the freeprojecting marginal portions f of the wrapper or cover blank over theopposite edges of and cause such portions to become adhesively affixedto the gummed marginal portions e, on the exposed face of the shellblank, as more clearly shown in Figure 3, thus making an assemblyconsisting of a shell blank and its applied wrapper or cover blank. Itwill be seen that the marginal portions 7, of the cover blank areextended so that they project over and cover a portion of the edges ofthe corner laps c, and in the finished box these covered portions lie inbetween adjacent faces of the multi-pl end walls.

The assembly having been formed as described, I then fold up, (or downas the case may be) the two covered side wings b, as shown in Figure 5,forming the side walls of the box shell, these walls being thencompletely covered including the turn in as clearly appears in thedrawing. This folding operation is preferably performed about an innersupport such as a form block or plunger. The corner laps c, at the oposite ends of the side wings I), are then in olded toward each other, asshown in Figure (3, the four corner laps being preferably inturnedsimultaneously. During the corner lap infolding operation, the portionsof the wrapper blank carried by the corner laps are also inturned andthe end wings d, simultaneously folded up against the infolded cornerlaps to produce the structure illustrated in Figure 7, it beingunderstood that as the corner laps c, and the end wings d, are folded asdescribed, the free portions of the wrapper blank at the corners of thebox are infolded in the form of gusset folds, so as to cause the latterto lie in between adjacent faces of the multi-ply end wall plies formedby the corner laps c, and the end wings d, the said infolded portionsalso covering the raw edges of the end wings of the shell blank, so thatno such edges are exposed.

As will be seen by referring to Figures 1 to 5 inclusive, the end wingsd of the shell blank are provided with adhesive all around the freemarginal portions thereof. This is done for the purpose of securelyattaching projecting side marginal portions 9 of the end wings of thecover blank when these portions are infolded as described, and also toprovide adhesive zones for maintaining the box shell in final set upform.

After the corner laps and end wings have been infolded in the mannerstated to produce the structure shown in Figure 7, the remainingupstanding marginal portions of the cover or wrapper blank at theopposite ends of the box are then inturned over the upper edges of andadhesively aflixed to the adhesive stripes or zones carried by the endwings and corner laps forming the end walls of the box shell to completethe covering and setting up operations.

A squeezing pressure is then applied to the inturned portions justdescribed to cause them to become more firmly affixed so that theinturned marginal portions may serve in and of themselves to maintainthe box in its final set up condition as illustrated in Figure 9, itbeing understood that all the folding and setting up 0 erations arecarried on very quickly aftert e shell blank has been stencilled andbefore the glue has had a chance to set or dry.

It will thus be seen from the foregoing procedure that my improvedmethod of making covered paper boxes differs very materially from allpreviously known methods, in that I first provide a substantially flatassembly consisting of a shell blank and a superposed cover blank, byapplying the required adhesive to a face of the relatively stiff shellblank and then combining the shell blank with the unglued wrapper blank,thus obviating the difficulties and waste which occur from curling whenliquid adhesive is applied to the thin wrapper or cover blank before itsapplication to the box shell as heretofore practiced.

My improved method also differs from known methods in that the marginaledges of the wrapper blank at the side siges of the shell blank areinturned over and affixed to such edges of the shell blank while thelatter is maintained substantially flat, or in other words. before theshell blank is folded into box form, and the marginal edges of the endwings of the wrapper folded over and affixed to the interior of the boxshell as a final step which completes the setting up operation andserves, along with the adhesively connected corners laps, to maintainthe folded shell into box form.

In Figures 10 to 18 inclusive I have shown the various successive stepsin the manufacture of another form or type of loose wrapped box madeaccording to my improved method. In this particular type of box thecorner laps are located exteriorly of the end wings of the shell blank,but they are covered by the applied wrapper or cover blank as will beseen.

In these figures, reference S designates the shell blank of relativelystiff box-board stock and W designates the wrapper or cover blank. Theshell blank S consists of a body portion a having integral side wings h,each having corner laps c at the ends thereof, and end wings d. Thecover or wrapper blank W is of general cruciform shape and side wingsare provided with transverse slits g spaced a short distance from theends thereof to provide lips or tongues h for a purpose presently toappear.

In making this style of box I proceed in precisely the same manner asheretofore described with reference to the box illustrated in Figures 1to 9 inclusive, by first stencilling the shell blank on one face aroundits marginal edges, then superposing the flat shell blank onto the flatcover or wrapper blank, then inturning the projecting marginal edges 7over the marginal edges of and adhesively affixing them to thestencilled edges of the shell blank, leaving the lips or tongues 72.projecting orlying in the plane of the assembly as shown in Figure 12.

The side wings b of the assembly are then folded up at right angles tothe body portion thereof and the end wings cl are likewise folded up,these operz-itions pref erably taking place while the embryo box shellis interiorly supported as by a form blank. here mechanical means areemployed to fold the assembly into the form of a box, the end wings arefolded up by lifting devices having engagement therewith while the sidewings are being folded and preferably during an advancing movement ofthe assembly.

The function of the free laps h is to cover the raw edges of the cornerlaps and the end wings adjacent the vertical box corners. These freelaps are inturned over the marginal edges of the end wings of the cornerlaps at the ends of the box at the same time the free marginal edges ofthe end wings of the cover blank are inturncd over such edges. It iscustomary in many types of loose wrapped boxes to fold the end wings ofthe cover blank in such a way that the edges thereof will be arranged onconverging lines as shown. By this arrangement the upper portion of eachfolded end wing is narrower than its base so that unless some provisionis made for covering the marginal edges of the shell blank at the endsof the box such edges would be ex posed, which would be objectionable.By slitting the cover blank at the points g to provide the free laps has described, prevision is made for covering those portions of themarginal edges of the formed box shell adjacent the corners, so that acompletely finished box results.

In Figures 19 to 27, inclusive, I have illustrated the various stepsperformed in making what is known as a tight wrapped box according to myimproved method. The term tight wrapped is employed because the wrapperblank is adhesively attached to the exterior walls of the box shellthroughout as distinguished from being loosely applied and unattached asin loose wrapped boxes.

In making these tight wrapped boxes according to my method I proceed insubstantially the same manner and employ substantially the same foldingoperations as carried out in making loose wrapped boxes except as to theapplication of the adhesive to the box shell and as to the folding ofthe corner laps which are shown as being arranged exteriorly of the endwings of the box shell instead of interiorly thereof as in'some of theother types of boxes.

As shown in Figure 19, the box shell. blank C consists of a body portion0:, having side wings I) h each having corner laps c at their ends andend wings d. The wrapper blank W is of substantially the same shape asthe box shell blank S except that the side wings are wider. than thecorresponding wings of the shell blank and the end wings thereof arepreferably of the same width as the corresponding wings of the shellblank but slightly longer so as to provide marginal portions that may beinfolded about the marginal edges of the shell blank and adhesivelyaffixed to the inner walls of the finished box.

Adhesive is applied to one face of the box shell blank around themarginal edges thereof at e", as shown in Figure 19, and the other facethereof is coated throughout with adhesive, as shown in Figure 20. Thetwo blanks are then arranged in superposed relation, the face of theshell blank that has been coated throughout being placed upon the upperface of the wrapper blank W to provide a flat assembly.

In'superposing the adhesively coated face of the shell blank S" upon theuncoated u per face of the wrapper or cover blank V6 in the productionof the assembly, provision is made for preventing adhesive at tachmentof intermediate portions of the end wings of the shell blank tocorresponding intermediate portions of the end wings of the wrapper orcover blank, in order to permit subsequent separation of the end wingsof the two blanks to provide what I have termed an offset method ofgluing the end wings of the cover or wrapper blank. That is to say,opposite end portions of the end wings of the wrapper or cover blank areprovided with adhesive which is received or taken from adhesively coatedportions of the end wings of the shell blank during the assemblyoperation so that the adhesively coated portions of the wrapper blankmay be adhesively attached to the uncoated portions of the corner lapsof the side wings, when such corner laps are infolded at right. anglesto their wings, in the formation of the box. This method of oflsetgluing I believe to be distinctly new and as it forms an important partof my invention I have claimed the same broadly in my co-pendingapplication Serial No. 431,910, filed December 20, 1920.

In practicing this part of my invention, by means of mechanicalinstrumentalities, I propose to interpose relatively thin plates Pbetween the end wings of the cover and wrapper blank, as these two arebeing superposed one upon the other, as shown in Figures 21 and 22,these plates being of less width than the width of the end wings of theshell and cover or wrapper blanks, so that, when the two blanks arebrought into superposed relation and pressed together to cause them toadhere one to the other, opposite end portions only of the adhesivelycoated end wings will contact with the corresponding portlons of the endWings of the wrapper or cover blank, the plates P holding theintermediate portions of the two blanks separated. The separating platesP are each provided with a longitudinal slot or o ening to permitsuitable grippers as hereinafter described, to pass therethrough andgrasp or grip the edges of the end wings of the shell blank and peel orseparate them from adhesive attachmentwith the end wings of the cover orwrapper blank, the latter wings being held down during the peeling orseparating operation by means of grippers 38, Figs. 23 and 33. Thispeeling operation, of course, takes place while the glue or adhesive isstill in a moist condition and separation of the blanks may therefore bereadily effected. As a result of the separation the opposite marginaledges of the end wings of the cover or wrapper blank are provided withspots or zones .90 of glue as illustrated in Figure 24, so that suchportions of the blank may be subsequently attached to inturned un-coatedportions of the corner laps as above described.

After the two blanks have been adhesively connected in the mannerdescribed, the projecting marginal edges of the side wings of thewrapper blank are then infolded over and adhesively afiixed to thegummed marginal edges of the side wings I)" of the shell blank as shownin Fi ure 22, thus completing the flat assembly. The end Wings d" arepeeled or separated from the corresponding wings of the cover or wrapperblank as previously described after the marginal edge turn in operationand during the assembly folding operation.

The side and end wings of the shell blank are then folded up at rightangles to the body portion, as shown in Figure 23, and are held in theirfolded condition in any suitable way, the end wings of the cover orwrapper blank, which have been'provided with ottset gluing, remainingflat, as shown in said figure. The projecting corner laps at the ends ofthe side wings are then infolded and held into adhesive attachment withthe adhesively coated faces of the end wings of the shell blank toprovide the structure shown in Figure 24, and while so held the endwings of the cover or wrapper blank are folded up and adhesivelyattached to the infolded corner laps and the exposed port-ion of the endwings of the box shell to provide the structure shown in Figure 25, theoffset glued portions now coming into play. Then the projecting marginalportions of the end wings of the cover or wrapper blank are then turnedover the marginal edges of the end walls of the box structure as shownin Figure 26, after which these mar al edges are turned down andadhesively a xed to the adhesively coated edges of the end walls tocomplete the setting up and covering operation and thus provide thecovered box as illustrated in Figur 27.

I prefer in all cases to perform the folding operations of the assemblyabout a formblock or plunger which is approximately the size, as toarea, of the body portion of the shell blank, the form-block or plungerconstituting an inner support for the box shell during the formationthereof, the employment of the box form insuring squareness of thefinished box and permitting pressure to be applied exteriorly of theshell while on the form.

I have illustrated and, described only one type of so-called tightwrapped box of which there are many, but it will be perfectly obviousfrom the disclosure that all types of both tight and loose wrapped"boxes may be made according to my method without departing from thespirit of the invention, the

essential feature in each case being the male ing of a substantiallyflat assembly from previously prepared shell and cover blanks, theassembly being then folded into box form, th operations of folding theassembly also serving to complete the application of the wrapper blank.

laving described the steps or operations performed in making severaldifferent kinds of boxes oi? the tight and loose wrapped type accordingto my invention, 1 will now proceed to described one type of mechanismfor performing my method by mechanical instrumentalities. Theseinstrumentalities in the. instance shown are arranged to produce asuccession of assemblies and deliver them successively to a mechanismfor fold ing them into box term. I do not wish to be understood,however, as limiting myself to the precise form of mechanismillustrated, as obviously other forms oi mechanism may be employedwithout departing from the spirit ot the invention. Nor do I wish to beunderstood as limiting myself to the employment in a single machine ofall the diliercnt mechanisms about to be described, as it will beperfectly obvious from the showing that some of the mechanisms beomitted entirely leaving others to perform useful functions inassociation with each other or in association with other mechanisms.

It will be apparent to those skilled in the art'to which my inventionappertaius, that the mechanism herein disclosed for making rlatassemblies from flat box shell and cover blanks, may be employed forthis purpose, whether the adhesive is applied to the shell blank or tothe cover blank, and this is espe cially true in the matter of preparingsemblics tor the manufacture of loose wrapped boxes where adhesive isapplied only to the marginal edges of one of the blanks. So far as I amaware I am the first in the paper box making; art to provide mechanicalmeans for preparing and assembling two :tiat blanks of the kind referredto in the manufacture of box forming assemblies, and wherein the blanksare maintained fiat or substantially so during the assembly formingoperations,

In making covered boxes of the loose wrapped type, according to my.improved method, it will be seen that no glue is applied directly to thethin cover or wrapper blanks, such as would have a tendency to cause theblanks to curl, this curling tendency theretore, with the obj cetionsand diliiculties resulting therefrom is entirely avoided by my method.In making tight wrapped boxes according to my improved method, onlyrelatively small spots or zones of adheslve are applied to the cover orwrapper blank, but these are appliedin such a way and at such a timethat no curling oi the blank is possible, since the end wings of thecover blank to which'the spots or zones of glue have been applied areheld from any curling tendency by the adhesive attachment of the wingsof the cover blank to the wings of the shell blank until. just prior tothe time when the cover blank wings are to be finally and permanentlyafiixed.

I do not lay claim in the present application to the box constructionsor the assembly or assemblies per so, as these are claimed in myco-pending applications, erial No. 235,515, filed May 20, 1918, SerialNo. 235,516, filed May 20, 1918 and Sci-1a] No.

One of the important advantages result ing from my improved method ofmaking covered paper boxes in the manner described resides in the factthat I am able to employ relatively light stock for the cover blanks,since I have entirely eliminated the troubles heretofore encountered byreason of the curling tendency oi the cover blanks in those methodswhere the adhesive is ap plied directly thereto. Where liquid adiesiveis applied directly to the cover blanks, according to the methodsheretofore employed, it has been necessary to employ relatively heavystock in order to lessen the curling tendency as much as possible. Aspaper stock is usually sold by weight, I am able, by reason of my newmethod, to utilize the lighter grades 01 covering papers and a mat .rialsaving in the cost of the finished product is thereby effected.

In Figures 28 to 36 inclusive 1 have shown one form of mechanism forcarryingout in simple manner and very expeditiously the requiredassembly forming and box folding operations,'only so much o1 the mechanism. being shown. as to give a clear understanding of the constructionand operation thereof and more particularly the construction andoperation oi the mechanism essential to the manufacture oi the fiatassemblies from which the boxes are to be formed. T his assembly formingmechanism is a machine complete in itself, but I have shown it inassociation with box forming instrumentalities so that the disclosure ofthe essential elements 01 a machine for forming completely covered boxeswill be complete. The box folding mechanism may, course, be varied tosuit the requirements, the mechanism shown being merely by way clexample.

According to the construction and plan of operation of the assemblyforming and folding mechanism illustrated, I provide a plurality ofstations arranged in series, each having devices thereat, or associatedtherewith, to perform a certain definite step or operation in theseveral steps or operations required to produce and deliver the finishedbox forming assemblies and for .tolding,- them into finished boxes. Theconstruction and arrangement of the various parts of the machine aresuch that the devices at several of the stations are each operating uponan assembly-element or elements at the same time, so as to increase thecapacity of the machine which may be said to be of the stage type. Themachine thus automatically produces a succession of finished assemblieswhich are automatically delivered to the box folding and setting upinstrumentalities where they are formed into finished boxes or covers asthe case may be.

In short, the mechanism is desi ed to produce a succession of embryo boxforming assemblies, each comprising a substantially flat box shell blankand an attached wrapper blank, and said mechanism includes a pluralityof stations, each having devices thereat or associated therewith forperforming a succession of assembly forming operations, and meansco-operating with said stations for transferring the assembly-elementsfrom one station to another in succession.

In the machine illustrated, I have shown three stations which co-operatein the production of the assembly, and have also shown in associationtherewith, a box forming station. For convenience of description I havelettered and will hereafter refer to these stations as follows:

A-shell blank supply station,

Bstencil and shell blank gumming station,

Cwrapper blank supply and assembly station,

D-box forming station.

A shell-blank stencilling and transporting device, and an assemblytransferrln device or carrier, are co-operatively associated with theassembly forming stations referred to. The shell-blank stencilling andtransporting device operates to carry the shell blanks successively fromthe shell blank supply station to the assembly forming station, and theassembly carrier or transferring device operates to transfer thefinished assembly and carry it into or partially through the box foldingmechanism, it being understood always that the assembly formingelements, i. e., the shell blank and the cover or wrapper blank, as wellas the assembly itself, are always maintained in a flat or substantiallyflat condition until the assembly is delivered into the box foldingmechanism.

The shell-blank transporting and the assembly transferring devicesoperate in con junction with the assembly forming stations to a plyadhesive to the relatlvely stiff shell blan either on one or both faoes,depending upon the style of box being made, then transfer the adhesivelycoated shell blank and deliver it flatwise onto its wrapper blank, andthen transfer the finished assembly to the assembly folding mechanism toform it into a set up and completely covered box.

The shell blank trans orting device A and the assembly trans erring orcarrying device B are both mounted upon a carriage 1, of any suitableconstruction, which carriage is preferably provided with anti-frictionrollers 2, which travel or ride upon a trackway or trackways' 3, thelatter being supported in any suitable manner as by rods 4. A verticallyreciprocating motion is imparted to the trackway 3, by any suitablemeans (not shown), so that as the trackway moves up and down, thecarriage with its transporting and transferrin devices A and move withit. In a dition to its vertically reciprocating movements, the carriageis mounted to travel back and forth horizontally upon the trackway ortrackways 3, these horizontal movements being effected by means of arock lever 5, having a link connection 6 with the carriage, as moreclearly shown in Figure 28. The horizontal movements of the carriagebring the shell-blank transporting device A and the assemblytransferring device B into cooperative relation with the severalstations A, B and C. Of course, the movements of the carriage are timedto co-ordinate with the movements of other parts of the machine as willhereinafter more fully appear.

The shell-blank transporting device A consists of a head carrying rubberor other glue applying stencil strips 7, adapted to apply the lines orzones of glue 6, to the upper face of a shell blank, and there is alsoprovided a combined shell-blank support and stripper plate 8, which isadapted to be housed within the boundary of the stencil strips 7, andwhich has a movement relative thereto, effected by any suitable means,such as rack and pinion mechanism 9, the said plate 8 being mounted upona rod 10. During the application of glue to the stencil strips, as willbe hereinafter described, the combined support and stripper plate isretracted in an elevated position above the plane of the under face ofthe stencil strips, but it is also adapted to assume a position insubstantially the plane of the stencil strips in order to constitute asupport for a shell blank when the latter is receiving glue over itsentire under face, as in the manufacture of tight wrapped boxes. It isalso adapted to assume a position below the plane of the stencil strips,as during the operation of producing the box forming assembly at theassembly forming station, as will presentl appear. The assembly carrieror trans erring device which is also carried by the carriage and movestherewith, consists of a pair of grippers of any suitable constructionand whlch may be operated in any suitable way to cause them to grip thetwo opposite end wings of with th l'oii o ii 1 n (Jilin i ll gull meansso that l owe L ,7 a new supply o l elevate the follower to i (l also nll i ll 011 113,

'l e stencil gumming' station B is situated talents in each of which ismounted a glue &-))l",'ll]9 roll indicated as and 31. L a

These 1 ils are mounted to rotate in opposite directions the roll 30rotating 1n an anti-clockwise direction and the roll 31 opcrating in aclockwise direction.

Where glue is placed in both compartments of the tank or pot, I preferto employ a relatively strong and quick setting glue in the compartmentin which the roll 30 rotates, and a weaker and more slowly setting gluein the compartment in which the roll 31 rotates. The reason for this isthat parts of the stencilled portions of the blank are employed in thesetting up or corner staying operation thus requiring a strong glue;whereas a weaker glue is all that is necessary to adhesively connect thetwo blanks of the assembly, and besides, peeling of the end wings in theoffset gluing operation as heretofore described, is more readilyaccomplished where a weak and slow setting glue is employed.

The station C, has located thereat the marginal edge turn-in mechanism,i. e., devices for turning the marginal edges f, of the wrapper blank W,over the opposite edges of and aflixing them by pressure to theadhesively coated edges of the side wings I), of the box shell blanks asheretofore described with respect to Figures 3, l2 and 22. Thesemarginal edge turning-in devices, as more clearly shown in Figures 31and 32, consist of a pair of fixed bars 32, with each of which isassociated a pivoted or hinged resser bar 33, the latter being arrangedwith relation to the bars 32 so that as the presser bars are rocked ontheir hinges or pivots, the free marginal edges of the wrapper blank ofan assembly situated therebetween will be inturned over and adhesivelyafiixed by pressure to the glue coated marginal edges of the side wingsof the shell blank, as previously described. The pivoted or hinged bars33 may be operated by any suitable means and by preference they are somounted as to be adjusted laterally to operate upon blanks of differentsizes. In the instance shown, each bar 33 is mounted upon a rock shaft34, journalled at its opposite ends in suitable bearings not shown. Thesaid shaft 34 carries a crank 34', to which is connected a link 34", andby which the shaft 34 may be rocked to cause the bars 33 with theirpresser blocks to inturn and aflix the marginal edges of the cover orwrapper blank to the stencilled edges of the shell blank. During thismarginal edge turning operation, the assembl is supported from beneathby means 0 the suction head 17 and from above by means of the ejectorplate 8, forming a part of the shell blank transporting device A, asshown in Figure 31. B reason of the fact that the assembly is rmly heldin a flatwise condition during the marginal edge turning-in operation, amore uniform and accurate turn-in is secured.

By referring to Figure 29 it will be seen that the space between thebars 32 of the marginal turn-in mechanism is less than the maximum widthor length of the wrapper or cover blank, but since these blanks areflexible, the said bars 32 offer no obstruction to the free passage ofthe wrapper blank therebetween, as the ends of the blank simply flex orbend as they are being carried upward between the bars by means of thesuction head 17. This head with the blank held thereto by suction ismoved up by means of the link 21 and lever 22 until it meets astencilled blank carried by the shell blank transporting device A,whereupon the two 'blanks are brought together in assembled relation.Then the trackway 3 with its carriage 1, moves downward as a unit for ashort distance, and at the same time the ejector plate 8 is caused tomove, by means of the rack and pinion mechanism 9, out of its housedrelation to the stencils 7, the said plate 8 and suction head 17 beingthen brought to a position to hold the clamped assembly in the plane ofthe upper face of the bars 32 of the marginal edge turn-in mechanism,this downward movement of the assembly causing the free marginalportions f, of the cover blank to engage the edges of the marginal edgeturnin bars 33, so as to fold the free marginal edges f, of the coverblank up at right angles to the body of the assembly, as more clearlyshown in Figure 32, after which the turn-in bars 33 are rocked toproperly bend and ailix such marginal edge portions of the wrapper b ankto the stencilled portions of the shell blank, completing the assemblywhich is then grasped by grippers 25 or 25 of the assembly transferringdevice at the proper moment to carry the same over to the box forminginstrumentalities, while the blank transporting device A is bringin afresh shell blank into position to be applied to a fresh wrapper blank.It should be understood that while the assembly transferring device andthe shell blank transportblank adjacent the corners of the box, as shownin said figures. These gusset or bellows-folds form a neat appearance inthe wrapper at the ends of the box, as more clearly illustrated inFigures 9 and 16. In making boxes of the type or style illustrated inFigure 9, the free portions of the wrapper blank at the ends of the boxadjacent the corners thereof are folded so as to lie in between thecorner laps and the end wings of the box shell blank, portions of thewrapper blank covering the opposite raw edges of the end wings of theshell blank.

An important feature of the mechanism and its operations is that thecorner lap turn-in wings 40 are caused to retain their hold on thecorner laps while the end wings are being folded up to position, thusgreatly facilitating the folding and setting up operation, the saidwings 40 being retracted just as the end wings assume their finalposition.

The me: hanism referred to for folding up the end portions of theassembly and forming the gusset or bellows folds as described, is moreclearly shown in Figures 6, 34 and 35, and consists of a pair oflaterally movable folding plates 42 and an intermediate folding plate43, said plates being mounted upon a squared shaft 44, the plate 43being fixed to the shaft 44 and the plates 42 being slidably mountedthereon, and each normally urged outward by means of a coiled sprin 45.One end of ear-h spring is attache to a block 46, carrying the centralfolder plate 43 and its other end is attached to a block 47 carrying itsassociated folder plate 42, each block 47 being mounted to movelongitudinally upon the shaft 44. In the folding operation the folderplates 42 are caused to move inward toward ea h other as said plates aremoved upward and they gradually resume their normal position as they aremoved outward and downward. To accomplish this operation I provide eachend of the squared shaft 44 with an eccentric 48, each mounted in abearing 49, carried by bracket arm 50, as more clearly shown in Figure6. Each bearing 49 is provided on its inner face with a cam projection51, arranged adjacent its associated eccentric and each folder plateblock 47 is provided with an outwardly projecting lug 52, which engagesor rides over the face of its associated cam 51, so that as theeccentrics are rotated in their bearings 49, the folder plates will moveupward in the arc of a circle and inward toward each other to effect thefolding operations, as more clearly shown in Figure 6. The means forrotating the eccentrics and the squared shaft 44 consists of a rotatingshaft 53, Figures 34 and 35, having a crank arm 54 at one end thereof,which arm acts upon a block 46, to which the central folder wing 43 isattached.

The end of the crank arm 54 in its travel through the are of a circle,contacts with the block 46, causing the shaft 44 to rotate, thuselevating the folding plates 42 and 43. The shaft 53 is rotated by anysuitable means not shown.

The end wings of the assembly having been folded up in the mannerdescribed and the gusset or bellows folds formed, (if the box is of thetype having bellows folds), the box then assumes a position illustratedin Figures 7, 15 or 25, depending upon the style of box being made. Thebox is then covered over its entire exterior and is complete except forthe operation of folding over and affixing the marginal edges of thewrapper blank to the inner walls at the ends of the box to complete thesetting up operation.

The plunger 36 now carries the box farther down and into a well, havingwalls 56, Flgure 28, and deposits it upon a suitable supporting plate57, as more clearly shown in Figure 33. Leading outward from the well56, is a channel formed as a continuation of the bottom plate 57, theopposite marginal edges of the channel being provided with fixed foldingwings 58, which operate during movement of the box to fold the proecting portions of the wrapper blank over the free edges of the boxshell end walls, bringing such edges to a position shown in Figures 8,16 and 26. The box is caused to travel through the said channel by meansof a plurality of pairs of fingers 59, which are arranged in spacedrelation to engage a plurality of boxes to move them through the channelsimultaneously by step movements, the fingers being mounted uponoscillating and longitudinally recipocating shafts 60. The shafts areoscillated in one direction to move the fingers outwardly away from theboxes and in the opposite direction to move them inwardly and intoengagement with the boxes, as they are successively delivered by theplunger 36 at the bottom of the well 56 adjacent the channel. Uponmoving through the folders 58 the boxes are delivered beneath a secondplunger 61, mounted upon a vertically reciprocating rod 62 andimmediately the box is positioned beneath the plun er 61. the latterenters the same carrying with it the turned over marginal edges of thewrapper. Arranged adjacent the walls of the box at this position of thechannel, is a pair of presser blocks 63, as more clearly shown inFigures 17 and 36, said blocks being operable to impart a squeezingpressure to those portions of the end walls of the box that have hadtheir marginal edges turned down by the plunger 61, this squeezingpressure operating against the plunger to firmly affix such marginaledges to the inner walls of the box. The plunger is then moved upwardout of the box more clearly shown in and the whole series oiboxes i inthe manner hereto? ing th t sisth upon fingers in over. walls o lon andtake oia; any outwi may be p sent in men i i. in the int tendency o thewalls bulge ihre outwari wrapp e. applie we to have lace *oaners or Jo,lira :7.

So far as I am aware I am the first in the box makingart to sele t, transport and assemble blanks in the manner described andI lay claim thereto broadly.

In making loose wrapped boxes of the type illustrated in Figures 1 to 9inclusive, wherein portions 9 of the wrapper blank W are inturn'ed aboutthe opposite raw edges of the end wings d of the shell blank, theinwardly and upwardly moving folder plates 42 shown in Figures 6 and 35have inturned lips 42' spaced from the plates proper, these lips beingadapted to engage the side marginal portions 9 of the wrapper blank andfold them about the opposite edges of said end wings (I to cover the rawedges thereof. In making boxes of the type illustrated in Figures 19 to27 inclusive, the plates 42 are not provided with the lips asdescribed,a flat plate being all that is required.

I do not claim in the present application the mechanism for making thebox-forming assemblies, nor do I lay claim herein to theinstrumentalities for forming the assemblies in box form, as suchmechanism and instrumentalities are claimed in my co-pending applicationfiled. September 16, 1921, Serial No. FOLOSS, although one form ofmechanism for carrying out my new method is already claimed in itsbroader aspect in my co-pending application.
